ZXT models
Three text assistants, one that sees photos, and an image maker. Pick a model by how fast you need the answer, how hard the question is, and whether ZXT needs to look at a picture.

What’s new
8 November 2026- ZXT V2, the vision model. Send up to four photos — screenshots, documents, handwriting, charts — and ask about them.
- ZXT Image. Ask for a picture (“make a picture of…”, “buatkan gambar…”) or pick Create image, and ZXT paints an original image.
- Smarter web search. ZXT searches only when a question needs it, and every site it read sits in one expandable step.
- Replies keep going. Switch to another chat while ZXT is answering — the answer is waiting when you come back.
- A calmer look. A classic stone-and-olive interface in light and dark, with fewer colours and less clutter.
- Help & support. Three Gmail addresses for problems and feedback — also listed in Settings.

Image creation is handled by ZXT Image and works from every chat model. Speed and context figures assume the reference build; smaller machines reduce context first, then speed.
02
Thinking
Thinking lets a model reason before it answers. The reasoning appears in a collapsible step above the answer — labelled “Thought for 12s” or similar — so you can open it or ignore it.
In the app, turn on Think beside the message box. ZXT 2 and ZXT V2 think only when it’s on, ZXT 3 always thinks, and ZXT 1 never does.
Level
Low
A short internal draft. Good for routine questions where speed matters.
Level · ZXT 3 only
Medium
Lets the model plan a couple of steps before answering.
Level
High
Extended reasoning. Slower, but better at maths, logic and multi-part prompts.
Web sources are cited in the answer, never inside the reasoning step.
03
Web search, files, photos and images
Web search
Turn on Search beside the message box. ZXT searches only when a question needs fresh information — greetings, small talk, coding and writing tasks never trigger a search.
Every site it read is grouped into one expandable Searched the web step, and the sources are listed with the answer. Works with every model; available in the app, not through the API.
Files
Attach up to 4 text files per message, up to 100 KB each, from the + menu. Plain text, Markdown, CSV, JSON, source code and similar formats work with every model.
Photos ZXT V2
Choose Add photos from the + menu, or drop pictures on the message box: up to 4 photos per message (JPG, PNG, WebP). Large photos are resized to 1600 px before upload.
Only ZXT V2 can read photos. If another model is active, attaching a photo switches to ZXT V2 for you; the text models never get the photo option.
Creating images
Just ask — “make a picture of a lighthouse at dusk” or “buatkan gambar kucing astronot” — or pick Create image from the + menu (or type /@). ZXT Image paints an original picture in a few seconds.
Formats: square 1024 × 1024, portrait 832 × 1248, landscape 1248 × 832. Each image has Download, Open and Copy prompt buttons. Requests that break the safety rules are declined.

Good to know
- The ZXT models are designed to run on hardware the owner controls. zxt-chat.vercel.app is the online edition — your chats are saved to your account so you can come back to them.
- Context limits are per request. Very long conversations are trimmed from the oldest messages first.
- Thinking levels trade speed for quality. When in doubt, leave it on Low.
- Only ZXT V2 reads photos. ZXT 1, ZXT 2 and ZXT 3 are text-only; attach text and code to them.
- With Search on, a greeting stays a greeting — ZXT only searches when the question needs fresh facts.
- Answers keep running in the background when you open another chat or project.
